Police arrested 31-year-old Allan Chiem at a home at Canley Heights about 12.30am on Sunday after inquiries.

He was taken to Fairfield police station where he was charged.

After being refused police bail on Sunday morning, Chiem’s lawyer Mohamad Sakr from Truth Lawyers said his client wasn’t required to appear on video link as no release application was going to be made.

Mr Sakr said he had spoken to his client twice on Sunday morning and there could be mental health issues and a release application “may be made” on the next occasion for rehabilitation “pending assessment by a professional”.

Chiem was ultimately refused bail and his matter was adjourned to Penrith Local Court for early next year.

Footage taken on Sunday showed a man disguised in black, climbing on top of the strip of shops where the couple’s store is located. The video was circulating on social media in the hours after the murder.

Police will allege Chiem was the man on the roof.

He lived with his parents at the time of the alleged offending. It is also understood he was a part-time bookkeeper.

Mr Sakr addressed the media outside court and said his client was “fine, just like any individual in custody would feel”.

He said a professional would be “engaged for the purpose of assessing my client’s mental health”.

On Sunday, local residents expressed their sadness over the deaths of the popular shop owners with Ben Keans saying “their impact was far bigger” than just serving fish and chips.

“They were the kindest people, the hardest workers,” he said.

“I can remember (Ms Gau’s) laugh like it was yesterday. There is so much emotion pouring out in this community.

“We don’t want this shop to be forgotten. We don’t want this signage to disappear.”

Jenny Loi, who had been a tenant of the couple’s for more than a decade said “they would look after me very well” and they were planning a trip back to Cambodia this Christmas.

“They are very kind people, very normal people. I don’t know what someone would want with them,” she said.
